A VERSATILE TIG WIRE FOR WELDING OF INCONEL 600 AND SIMILAR COMPOSITION ALLOYS.
IDENTIFICATION
Getig 821, ERNiCr3
CLASSIFICATION
AWS/SFA 5.14: ERNiCr3, BS 2901-90 NA 35m
DIN 1736- 85 WSGNiCr2ONb Worst-off no 2.4806
DESCRIPTION
Getig 821 is intended for welding Inconel 600 and similar composition alloys. The deposit tolerates high dilution levels and is very resistant to hot cracking. It is not susceptible to sigma phase embitterment or carbon migration and is therefore ideal for service at elevated temperatures. The weld metal passes X-ray quality.
